The answer to this problem is m+5.
To solve, layout your equation, 4m+5-3m. Now, we cannot subtract a number from a variable, but we can subtract a variable by variable. This will be m. Or 1m. Since 4m-3m is 1m. You don't need to write m as 1m or any variable since it's one. Now add 5, which you cannot do, so the answer is m+5.
